Prestotwin - Combined fow - blocking - valves
Principle
Prestotwin are multi-function fttings combining fow control and
blocking. This avoids the requirement for two function fttings offering
a compact solution with signifcant space saving. They meet the
requirements for a safety ftting and incorporate the facility to accurately
control the piston rod speed.
Operation
PBVF4PK Flow regulator + blocker
• The pilot signal acting on the diaphragm keeps the poppet valve
open.When the pilot signal is removed the spring closes the poppet
valve.
• Flow control is obtained by the adjustment of the rotating barrel
against a ball bearing.
• The fow control locknut ensures the optimum setting is maintained.
